Patented June 20, 1939 UNITED STATES PATENT OFF-ICE 6 Claims.

'My invention relates to improvements in a backhand pencil pointer, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a backhand pencil pointer that is designed to be worn on the back of the hand where it is instantly available and yet where it will not interfere with the normal use of the hand during drawing. The device is yieldingly secured to the hand and carries a pencil pointer and wiper. A number of pieces of sand paper are carried by the pencil pointer and a trough is arranged around three edges of the uppermost layer of sand paper for catching and retaining the graphite removed during the sharpening of the pencil point. The pencil point wiper is used for wiping off the pencil point after it has been sharpened. The wiper may consist of a piece of lambs wool, felt or the like.

The entire device is extremely simple in construction and it provides a novel means for permitting a pencil point to be quickly sharpened and cleaned. The device will prevent any loose g5 graphite from dropping down upon the drawing material.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 shows the device operatively app-lied to the back of a hand;

Figure 2 is a full size plan view of the pencil point sharpener and wiper;

Figure 3 is a section along the line 3-3 of Figure 2; and

Figure 4 is a section along the line 4-4 of Figure 2.

In carrying out my invention, I provide a supporting band indicated generally at A that is designed to encircle the hand. The portion of 5 the band that extends across the back of a hand in Figure 1, is preferably made from chamois and is indicated at I. It is obvious that any desired material may be used. The piece of chamois l is substantially triangular in shape with the truncated apex of the triangle disposed near the side 2 of the hand and the base of the tri angle extending across the hand where the thumb 3 joins the hand. The band A includes an elastic strip 4, shown by dotted lines in Figure 1, and

the strip extends from the apex 5 of the piece I to the corner 6 of the base I of the same piece I. A second elastic strip 8 extends from the corner 9 of the piece l to substantially the mid point of the strip 4. The two strips 4 and 8 are connected together at Ill. This arrangement .per- '5 mits the support A to be placed upon the-hand and to be yieldingly held in place. The thumb 3 acts as an anchor for preventing the accidental slipping of the band A on the hand.

Figure 2 shows the piece I carrying a pencil'lO point sharpener indicated generally at C and a pencil point wiper indicated generally at D. The pencil point sharpener C is shown in section in Figures 3 and 4, and it comprises a frame H attached to the piece I in any manner desired, 15 such as by stitching l2, see Figure 3. The frame II has a bottom 13 and a side wall I 4 that extends around three sides of the bottom. A flange 15 extends inwardly from the side wall 14 and is spaced above the bottom l3 for providing a 20 compartment for receiving a plurality of pieces of sand paper shown at IE. In Figure 3 I show three pieces of sand paper superimposed one above another. A rim I'l cooperates with the flange Hi to form a trough that extends along 5 three sides of the frame II. This trough is for the purpose of catching and holding any loose graphite that has been removed from the pencil point during its sharpening. The graphite will therefore be prevented from falling down 30 upon the drawing material.

I also show in Figures 2 and 3 the wiper D. In the present instance the wiper comprises a piece of wool with the skin I 8 thereof, stitched or otherwise secured to the piece I at IS. The 5 hair 20 of the wool extends upwardly from the skin 18 and provides a surface that will retain any graphite rubbed off from the pencil point.

It is obvious that felt or any other suitable material could be used. A space 2i is provided be- 40 tween the pencil point sharpener C and the wiper D to permit the pieces of sand paper I6 to be removed and a new supply substituted.

From the foregoing description of the various parts of the device, the operation thereof may 5 be readily understood.

The device is worn in the manner shown in Figure 1 and is ready for instant use. The normal position of the hand will swing the pencil point sharpener C into an inclined plane and this 50 will dispose the trough 22 at the lower edge of the device C where it will catch and retain any loose graphite. The trough 22 has inwardly extending end portions 23 shown in Figures 2 and 3. This is for the purpose of closing the ends 55 of the trough and preventing any graphite from moving to the ends of the trough and escaping.

The wiper D has end tabs 24 that extend to the point sharpener C. These tabs prevent any graphite that drops onto the space 2|, from passing onto the drawing. The elastic strips will permit the device to yieldingly fit hands of diflferent sizes and these strips will hold the device securely on the hand. The wiper D is placed at a convenient distance from the sharpener C where it may be used immediately after the pencil point has been sharpened.

While I have shown only the preferred form oimy invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim:

1. A backhand pencil pointer comprising a support adapted to be removably secured to a hand, a pencil point sharpener secured to a portion of the support that extends across the back of the hand, and a pencil point wiper secured to the same portion and being disposed'near the pencil point sharpener, the edge of the wiper disposed nearest the sharpener constituting a retaining member for any graphite freed from the sharpener.

2. In a. device of the type described, a pencil point sharpener comprising a frame having a compartment for receiving pieces of sand paper, and a trough extending around the greater portion of the edges of the sand paper for catching loose graphite.

3. A backhand pencil pointer comprising a support adapted to be yieldingly secured to a hand, a pencil point sharpener secured to the support in a position to overlie the back of the hand, a piece of sand paper carried by the pencil point sharpener, and a trough extending along certain edges of the sand paper for receiving loose' graphite.

4. In a device of the type described, a support, a pencil point sharpener secured thereto and comprising a piece of said paper, a graphite retaining trough extending around three sides of the sand paper, and a pencil point wiper secured to the support and being spaced a slight distance away from the sharpener to constitute a graphite retaining member for the fourth side of the sand paper.

5. A backhand pencil pointer comprising a piece of material designed to overlie the back of a hand, elastic strips secured to the material and adapted to extend across the palm of the hand, said strips providing a thumb receiving opening, a pencil point sharpener secured to the piece of material and having a compartment for receiving a plurality of layers of sand paper, a trough extending around three sides of the sand paper for catching loose graphite, the pieces of sand paper being removable from the fourth side, and a pencil point wiper secured to the piece of material and being disposed near the fourth side of the pencil point sharpener, but allowing sufiicient space for the renewal of the sand paper, said wiper also constituting a graphite retaining member for the fourth side of the sand paper.

6. A backhand pencil pointer comprising a support adapted to be yieldingly secured to a hand, a pencil point sharpener secured to the support in a position to overlie the back of the hand, a piece of sand paper carried by the pencil point sharpener, and a trough extending along certain edges of the sand paper for receiving loose graphite, the ends of the trough being closed.
